Example XMM-Newton image and radial profiles of the newly-observed cluster PSZ2 G077.90–26.63, detected at an S/N ∼ 178 in the [0.3 − 2] keV band in the [0.15 − 1] R₅₀₀ region. Top left: [0.3–2.0] keV image, with green circle indicating R₅₀₀. Top right: raw temperature profile (black points) with best-fitting deconvolved, deprojected 3D model and corresponding 1σ uncertainties (envelope). Bottom left: scaled pressure profile compared to the universal pressure profile of Arnaud et al. (2010, APP10) and the mean stacked profile of Planck Collaboration Int. V (2013, PIPV). f(M) is a (small) correction for the mass dependence in the pressure profile shape (see Arnaud et al. 2010). Bottom right: scaled hydrostatic integrated mass profile compared to the best-fitting NFW model with concentration .
